To remove the front differential on 1991-1994 models, first raise the vehicle and then install jackstands. The driveshaft should be disconnected, brake calipers removed, tie-rod ends detached, and stabilizer bar taken out. The coil spring could be compressed with a floor jack, after which it can be removed and thereafter the shock absorber can be dismantled. Remove the radius arm including its bracket followed by the pivot bolt. While 1995 and later models only require loosening lug nuts to raise the vehicle and remove the wheel(s), caliper, and brake disc. Disconnect the ABS sensor, remove the hub drive axle/nut, and support the lower control arm. Remove the control arm balljoint nut plus stabilizer bar and pry the inner CV joint assembly. Press out the drive axle from the hub then disconnect the front driveshaft. Support the differential, remove mounting bolts, and pull out axle. Put in new circlip, grease differential seal lips before inserting stub shafts. Do not forget to tighten all bolts/nuts properly!

After securing the vehicle on jackstands, the rear wheels, rear spare wheel/tire, axleshafts, and the rear of the driveshaft need to be removed. These components must be removed to access and detach the axle housing from the vehicle.

For spindle bearing and oil seal replacement, the spindle is placed in a vise, and the bearing and oil seal are removed with a slide hammer and puller attachment. This may be necessary due to wear or damage, and the replacement ensures proper functionality.
